Found a clean 6.0l 2003 Excursion 4x4 with low miles, no current issues and a pretty attractive price. If I put $5k into all the typical upgrades/fixes would I be out of the woods or still sitting on a time bomb?

Looking for a stock daily driver and occasional tow vehicle for 6k trailer, nothing hopped up

I've had my 04 going on two years now and I did all the preventative maintenance, like studs and blocking off the egr and thus far no major issues (knock on wood). Watch this guy on youtube, he explains everything you'll need to know about the 6.0...

The videos were great. Sounds like he is recommending the 6.0l upgrades regardless of the model year if you're going to keep the vehicle for a while. I was under the impression the 2005's were not so much of an issue as the 03's. Guess not?

My box stock 06 6.0 just turned 94k miles/3000 hours. OASIS reports one injector replaced at 50k miles before I got it. Otherwise, it's been change the oil regularly, and go. I didn't mod the engine, because I got it to haul loads and it does just fine with 325hp. If I want to haul butt, I have something a lot faster.

However, if you do want to boost power, then the studs/egr delete are necessary, as is a larger exhaust, a proper set of gauges, and a thorough understanding of what you can and can't do. If you just plug in a tuner, set it to 'maniac', and floor it, you'll be looking for a new engine before long.
